Question

The angles with measures x and 4x are complementa angles.which is the value of x

Answer 1

`\huge\boxed{x=18^o}`

Explanation:

Two angles are Complementary when they add up to 90°.

Therefore

`x+4x=90\qquad|\text{combine like terms}\\\\5x=90\qquad|\text{divide both sides by 5}\\\\(5x)/(5)=(90)/(5)\\\\\boxed{x=18}`
